The other day, I’ve wrote about POWER8 ‘feature’ which requires from an administrator update of access keys in order to keep a server eligible for the firmware upgrade POWER8 – No hardware maintenance-no firmware upgrade . An administrator needs to enter these every few months, if a maintenance contract is re-signed every few months. This can be a headache, or something bigger if someone runs multiple servers. There is a secret HMC function, which can update the keys automatically.

By the command below an LPAR can be created with specific WWPNs, of course if you use NPIV adapters. It can be useful for LPARS migration between servers. It is extremely dangerous command, therefore it should be used only by people who knows what is for. Read more of this post

I would like to bring to attention installation order of fixes for the HMC firmware 8.8.2. If you install the fixes in incorrect order, you might loose the RMC connection to all AIX/VIOS hosts.

In my previous post I’ve mentioned about the new HMC feature which can adjust CPU frequency. In this article I want to describe how to speed up the POWER system box, get more performance from the system. It is very easy to overclock the machine.

In this post I give you a hint how to display a log which is usually used by IBM support to identify a serious hardware error. Such information usually can be found in HMC log called iqyylog. Usually, when you get that kind of hardware error, you involve IBM support. Very likely, they will ask for PE debug data. There is a way how to display the log by yourself. Remember, such information is very technical. But maybe you find it useful.
- First, you need to create the hscpe account on the HMC (if you haven’t done it). You can find the process here.
- Log in to the HMC GUI under hscpe account.
- In the Service Management menu you find three new options available
If you click on View Management Console Logs, you are going to see the log.

Since HMC firmware version 7.7.7, IBM added very cool feature, which allows installation of the Virtual I/O Server directly from the HMC. This is very convenient when you get your POWER machine to the new location, and you want to install an operating system, for instance, IBM i or AIX, but you prefer to do it remotely.
